Carbide burrs are tools used for deburring most hard materials like ceramics, stone, steel, aluminum, plastics and hardwood. They provide precision, which enable it to double in cutting, shaping, grinding and chamfering hard materials.
Carbide burrs can be used on a various materials including metals (including Steel aluminum and iron) and many types of types of wood. Quite a few on acrylics, fiberglass and plastics too. Carbide burrs will last for a long time without chipping or breaking to ensure it’s so competent to utilize them on soft metals like gold,platinum and silver.
Which are the Advantages of Carbide Burrs Compared with HSS Burrs?
Weighed against HSS, Carbide Burrs are much harder.
The Tungsten Carbide is extremely hard to enable them to provide in wider variety of work than HSS (Broadband Steel).
HSS can’t be as good as carbide burrs when they are at hot temperature. Carbide Burrs can bear hotness which enable it to run for extended time.
Carbide won’t soften at warm but HSS burrs is opposite. No doubt that carbide is the perfect choice.
How to Use Carbide Burs:
For further stability, insert the accessory bit in to the unit and then back out slightly before tightening on the collet nut or keyless chuck.
Avoid using these for drilling holes or enlarging holes which are lower than twice the diameter in the cutter. The tungsten carbide surface can easily catch along side it of a hole and break the part.
Use higher speeds for hardwoods, slower speeds for metals and slow speeds for plastics (in order to avoid melting at contact point).
Start at the lower speed. Then increase for the speed that offers probably the most favourable results.
Usually do not apply excessive pressure. It might slow down the spindle and chip cutting edges. Let the bur do the cutting.
Make use of the sides from the cutter for effective cutting. The tip cuts poorly and can break under time limits.
Never in-capsulate the bur inside the cut. If chattering occurs, increase speed.
When using aluminium and magnesium, consider some form of lubricant, wax or tallow, as it may help avoid the flutes from loading or packing.
Carbide burs, if used the proper way, will outperform HSS burs by 50
